Starting in Docker container: Error initializing core about vault

[heytrav]

I added --cap-add IPC_LOCK as in the other #59 and it worked.

I'm attempting to follow the tutorial using a ubuntu:trusty Docker
container and am getting the following error when I try to start vault:

root@31a7d422e87f:/# vault server -dev
Error initializing core: failed to lock memory: cannot allocate memory

I'm not sure if this is due to Docker, or if there is something special
about memory allocation in general in Docker that needs to be done here so
vault will work.

Here is the Dockerfile

Thanks! Closing as a duplicate.

@heytrav Its not a bug, you need to give your container the MLOCK cap

I figured it would be something like that. I just hadn't run across this in Docker before and wasn't sure.
